Use the newly added SYM_CODE_START_LOCAL* to annotate beginnings of all pseudo-functions (those ending with END until now) which do not have ".globl" annotation. This is needed to balance END for tools that generate debuginfo. Note that ENDs are switched to SYM_CODE_END too so that everybody can see the pairing. C-like functions (which handle frame ptr etc.) are not annotated here, hence SYM_CODE_* macros are used here, not SYM_FUNC_*. Note that the 32bit version of early_idt_handler_common already had ENDPROC -- switch that to SYM_CODE_END for the same reason as above (and to be the same as 64bit). While early_idt_handler_common is LOCAL, it's name is not prepended with ".L" as it happens to appear in call traces. bad_get_user*, and bad_put_user are now aligned, as they are separate functions. They do not mind to be aligned -- no need to be compact there. early_idt_handler_common is aligned now too, as it is after early_idt_handler_array, so as well no need to be compact there. verify_cpu is self-standing and included in other .S files, so align it too. The others have alignment preserved to what it used to be (using the _NOALIGN variant of macros).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
